Most dogs listed as Cattle Dogs are Australian Cattle Dogs, often called Blue or Red Heelers, or mixes with one. The label can also cover Texas Heelers and crosses with Border Collies or Labs. The Australian Cattle Dog was developed in nineteenth-century Australia to drive cattle by nipping at their heels, which explains the stamina and the independent streak.
Medium-sized, muscular and short-coated, these dogs usually weigh 30 to 50 pounds and live 12 to 16 years. Many bond hard with their people and stay reserved with strangers. In Fishers, that often means a dog that watches the cul-de-sac closely and wants to join every errand. Mixes vary in size, coat and energy, so a dog's behavior tells you more than its label does.
